Tomy stretch-legged Stoomdorm

Air pump powered fun! Me and and brother both had one of these cool gizmos. His (the Hoomdorm) hopped, mine (the unusually named Stoomdorm) scooted across the floor like a robotic rodent on steroids. Apparently they were marketed as "Space Pets". Weird.

Just pump up this bad boy and watch it clatter away, bringing unbridled carnage to livign rooms across the country. If you thought toy cars were a trip hazard, well these fellas moved so fast that the trip-factor increased tenfold. Probably.

I couldn't find a modern equivalent "Space Pet" - this thing below is the closest I could find.
